Abstract: Methods, systems, apparatuses, and computer program products provide network function selection for user equipment via a gateway network node. In an implementation, a single-network slice selection assistance information (S-NSSAI) list is received from a user equipment (UE). Additionally, it is determined whether a network node does not support a non-access stratum node selection function for the UE. Based on a determination that the network node does not support the non-access stratum node selection function for the UE, an initial UE message configured with an information element for the S-NSSAI list is generated, and the initial UE message is caused to be transmitted to a gateway network node to select a core network function for the UE.
